Report Model "Folder" vs "Perspective"

Can someone explain why I might use a Report Model "Perspective" rather than a Report Model "Folder"?

TIA!!!

Could you be more specific?|||

hi brian,

Let me explain the difference between them and then i will get back to your question.

1) In Report Model an entity can appear in multiple perspectives, but can reside in only one folder. you cannot have one entity in multiple folders.

getting back to your question .....

Lets consider a senario where you have a accounting department (account entity)and Packaging department ( Packaging Entity ) trying to access the customer entity.

If the Customer entity is in a folder and this folder exists in the accounts entity, then the customer entity will not be visible in the Packging entity.

So keeping a entity in a folder acts like a security mechanism.
So if you think that an entity will be accessed by multiple entities then it makes sence to keep it in perspective.

the second reason could be :

2) Security Roles can be assigned to entity folders but not to perspectives.
